Siemens SLIM Loop Isolator Module, Installations Instructions

Installation Instructions SLIM Isolator Module Model SLIM Loop Isolator Module from Siemens Building Technologies Ltd short circuits on FS 250C analog loops By placing devices between SLIMs installation a short in the wiring within that group is disconnected from the of the loop The of the devices to operate The operates in both A and Class B LINE 1 LINE 2 LINE 1 LINE 2 yellow LED flashes a device detects a circuit The SLIM isolates that part of loop When the short removed the SLIM restores 1 SLIM 1 Loop Isolator Module loop to normal operation The SLIM does not have a loop address and therefore not require address programming nor does it reduce the loop capacity below devices all system power before installation first the battery and then the AC SLIM is a polarity insensitive module Refer to Figure 1 for the location of the two terminals and two output terminals Line 1 and Line 2 can be either line of the SLIM may be used in two circuit configurations as follows B Figure 2 In Class B wiring each SLIM isolates a branch on the circuit Note that short on the main branch causes the entire loop to fail To prevent this mount the at the enclosure and run each branch independently 315 049692C 1 Building Technologies Safety All wiring must comply with and local codes order to provide adequate it is recom that you do not more than 20 devices a single SLIM Minimum wire gauge is AWG The total wire resistance wires between SLIMs exceed 20 ohms Do not install more than 15 per FDLC loop All circuits are supervised Refer to FDLC Installation P N 315 or the FS 250C P N 315 049589C the list of compatible as applicable All terminals are power A Single Loop All wiring must comply with and local codes order to provide adequate it is recom that you do not more than 20 devices a single SLIM Minimum wire gauge is AWG The total wire resistance wires between SLIMs exceed 20 ohms Do not install more than 15 per FDLC loop All circuits are supervised Refer to FDLC Installation P N 315 or the FS 250C P N 315 049589C the list of compatible as applicable All terminals are power LOOP 1 2 OUT OUT OUT OUT OUT OUT 2 Wiring Diagram Class B Installation Figure 3 In Class A wiring the SLIMs are wired in series with the loop wiring results in a single continuous loop If any group in the loop has a short that is lost and a Class A circuit failure results FS 250C displays the message Open and response for in the groups on the loop that follow the short ENCLOSURE ANALOG RETURN 2 1 1 2 ANALOG FEED IN OUT OUT IN OUT OUT IN OUT OUT 3 Wiring Diagram Class A Installation Single Loop Building Technologies Safety 315 049692C 1 Installation Figure 4 a standard 3 1 2 inch deep double gang electrical switchbox or a 4 inch electrical box that is 2 1 8 inches deep the field wiring Press the SLIM into the box and fasten the module to the box the module front plate with the plate supplied and fasten with screws RATINGS power VDC 1mA max SQUARE BOX 1 8 INCHES DEEP IM GANG BOX 1 2 INCHES DEEP IM SQUARE 4 SQUARE Building Technologies Safety 315 049692C 1 Building Technologies Ltd Kenview Boulevard Ontario L6T 5E4 315 049692C 1
